I just got started with vaadin i went through the Address-book application and I loved it.
Currently i’m building a web application that will be used for commercial proposes and i’m using vaadin to create the front end and I know that vaadin is open source but i don’t know if i can use some of the icons that came with the address-book demo app in my application or if they are copyrighted
Thanks in advance. and if you know about ny source when i can get opensource icons especially related with healthcare please let me know
